Abstract
The present invention provides a method, respective apparatuses, system and computer program product for obtaining channel state information in a coordinated multi-point transmission/reception communication network. The method includes allocating a first sounding resource to at least one of a plurality of user equipment in a coordinated multi-point transmission/reception communication network for transmitting sounding reference signal to a base station of a serving cell, and allocating a second sounding resource to the at least one user equipment for transmitting sounding reference signal to a base station of an interfering cell, wherein the first and the second sounding resource are different from each other.
